Smart Shoes Soon to Debut

A running shoe will soon not be just a running shoe any longer. Through a combination of sensor technology, wireless communication and Smartphone apps, the humble running shoe is being transformed into a monitoring device. According to Jesse Emspak, writing for LiveScience, the new running shoe will monitor how and where the runner’s foot hits the ground, how often, and if the gait is correct.

The Fraunhofer Institute in Germany has partnered with other universities and a shoe manufacturer to create a running shoe that has sensors to transmit data to a Smartphone and then on to a computer. The shoes are expected to be smart enough to inform their wearers how to improve their technique and avoid injuries.

Emspak reports that the shoe’s sensor logs data about the runner’s foot speed as it hits the ground, as well as its orientation in space, the duration of contact with the ground and the runner’s stride length. If the phone is out of Bluetooth range, the shoe will also store the data.

That data enables the software to calculate the forces acting on the foot. “It will tell you if the gait is correct,” said Dr. Andreas Heinig, a scientist at Fraunhofer who manages the wireless Microsystems group (www.runsafer.eu). “The running provides real-time feedback.”

Emspak wrote that there are still experiments to be done to improve the technology before it becomes available to consumers. The shoes could be on store shelves within two years, Heinig told LiveScience.

A U.S. company, Pegasus Sports Performance, Inc. has developed a shoe sensor that, it says, measures eight aspects of the foot’s motion as it hits the ground, including the dynamic of the kick. Pegasus’ system also links to a Smartphone and the Internet.

“Ceramic-ceramic is a good option for the young, active patient. It is wear resistant, has improved lubrication, and allows thin inserts for large heads,” argues Carsten Perka. “Ceramic has long been on a steady decline,” says Robert Barrack. “There are malposition issues (leading to impingement and potential for failure), liner breakage and mal-seating and squeaking. Why pay more for something that is not improved?”
